DSP与Simulink设计之CMD文件

2万 · 2012-12-3 23:22

1 概述
基于Matlab的Simulink生成的CMD文件根据系统定制配置，只限于在RAM中运行。
目的：更改CMD文件，程序烧写到FLASH中运行。
2 Simulink生成CMD介绍
生成的CMD文件在RAM中运行，无法烧写到FLASH中运行。
（1）此段CMD文件为Simulink自动生成的文件。

3 解决方案
从Simlink生成的CMD文件入手，更改配置，烧写到FLASH。
只需更改前导部分CMD文件afe_dsp.cmd，更改如下：
MEMORY
{
PAGE 0:
BEGINRAM: origin=0x0, length=0x2
RAMM0: origin=0x2, length=0x3fe
RAMH0: origin=0xa000, length=0x2000
OTP: origin=0x3d7800, length=0x800
FLASH: origin=0x3e8000, length=0xfff6
BEGINFLASH: origin=0x3f7ff6, length=0x2
CSM_PWL: origin=0x3f7ff8, length=0x8
BOOTROM: origin=0x3ff000, length=0xfc0
RESET: origin=0x3fffc0, length=0x2
VECTORS: origin=0x3fffc2, length=0x3e
PAGE 1:
RAMM1: origin=0x400, length=0x400
RAML0L1: origin=0x8000, length=0x2000
}

}
-l "C:\Program Files\MATLAB\R2009a\toolbox\rtw\targets\ccslink\ccslink\c2000\c280xPeripherals.cmd"
更改部分：
（1）RAMH0改为 FLASH
（2） .econst: > RAML0L1, PAGE = 1改为 .econst: > FLASH, PAGE = 0
4 结论
完成Simulink生成的CMD文件的配置更改，满足了应用要求。

还可以通过Simulink进行配置，双击板子，在Sections中配置。
